38 THE ENTOMOLOGIST. 



sexes of A. mercuriale were taken in the New Forest between 

 May 25th and 28th, and the species was still on the wing in the 

 beginning of August. Mr. Stewart took Enallagma cyathigerum 

 in Eenfrewshire, near Paisley, and Messrs. Ashdown and Bishop 

 captured it, on July 7th, at Frensham Great Pond. Mr. McArthur 

 captured for Mr. Briggs twenty-four specimens at Stornoway — 

 twenty males and four females. The specimens were of good size, 

 and in most cases the spot on the second segment was large — in 

 one or two cases similar in shape to that on the specimen figured 

 in the Ent. Mo. Mag. for 1890, p. 110. On June 26th, at Byfleet 

 Canal, I noticed a pair united per collum, and settled upon a leaf 

 of Potamogeton, in which the female seemed to be ovipositing 

 without going below the surface of the water. 



DESCRIPTION OF A NEW SPECIES OP GALL-MAKING 

 CYNIPIDiE FROM THE N.W. HIMALAYAS. 



By p. Cameron, 



Callirhytis SEMiCARPiroLiiE, sp. nov. 

 Ferrugineous ; the antennae, except the basal two joints, the head, 

 the greater part of the middle lobe of the mesonotum, the scutellum, 

 median segment, the pro- and mesopleurse, except above and the back 

 of the abdomen, black; the legs lighter coloured than the body, with 

 the tarsi and hinder tibife darker ; the wings clear hyaline, the nervures 

 blackish, the cubitus paler. J . Long. 2-5 mm. 



Hah. North-West Himalayas. 



Antennae bare, as long as the body. Head shining, finely acicu- 

 lated, bare. Except at the base, the middle lobe of the mesonotum is 

 rather strongly transversely striated ; the lateral lobes are minutely, 

 obscurely punctured. The parapsidal furrows are complete. Scutellum 

 irregularly punctured, its sides at the base are bordered by shining, 

 smooth furrows ; in the middle at the base are two narrow, longish 

 fove^e. The scutellum is roundly convex, and is not much raised 

 above the level of the mesonotum. On the base of the median seg- 

 ment is a smooth, shining semicircular broad keel, which is not quite 

 so broad in the middle as on the sides. The upper edge of the pro- 

 pleurge and the mesopleurse at the base above are rufo-testaceous. 

 The median segment bears a thick, white pile. Abdomen smooth and 

 shining ; the base and ventral surface are broadly black. The legs 

 have a microscopic white pile. Wings long and narrow, clear hyaline ; 

 the transverse cubital nervures and the cubitus are paler than the 

 others. The areolet is completely closed, slightly oblique, and 

 triangular. 



The third joint of the antennae is not much longer than the fourth ; 

 the tarsal claws are unidentate ; the antennae are slender and do not 

 become thickened towards the apex ; the radial cellule is long and 

 narrow and is not quite closed at the base, the nervure being faint
